ATTACHMENT FOR CORN BINDERS.

Application filed September 8, 1926. Serial No. 134,203.

A further object of the invention is to provide a device of thischaracter which supplements and increases the resistance of the tripelements which control actuation of the corn binder until the properbundle has been assembled.

A further and more specific object of the invention is to provide aswinging arm which may be readily attached to a normal part of the cornbinder and be positioned substantially immediately above the bin dingcontrol trips, so that corn which is at an inclination, in enteringbetween the boards of the binder, will first engage with this arm and beheld thereby to prevent its engagement with the trip arm until theproper amount of corn has been gathered. 7

These and other objects I attain by the construction shown in theaccompanying drawings, wherein for the purpose of illustration is showna preferred embodiment of my invention and wherein Figure 1 is aperspective view of my attachment applied to a corn binder, the binder 1being shown in dotted lines;

Figure 2 is atop plan view of the attachment, the supporting rod and thepivot pin being in section.

Referring now more particularly to the drawings, the numerals 10 and 11generally designate those portions of corn binder mechanism, known'asthe upper and lower trips. The function of these parts is to release thebinder mechanism for operation and they are operated by engagement ofcorn therewith. The binder mechanism includes a vertically extendingbrace 12 which is arranged at the right hand. side of the machine andserves to hold the right hand top board 13 in its elevated position.Upon this brace, I pivotally secure an arm let, so that it may swing ina horizontal plane. The arm 14: is

preferably in the form of a flat strip, one end passage of arms ofU-bolts 19, whereby they may be secured against the support 12. Thisarm, when properly positioned, is arranged above and slightly in advanceof the trip arms 10 and 11.

The binder mechanism further includes a brace 20 which is arranged inadvance of the brace 12 and at substantially the same level as the armwhen in properly applied position. To this brace, I connect one'end of aspring 21, the opposite end of which has engagement with the arm 14intermediate the ends thereof, such that it may be adjustedlongitudinally of the arm to vary the tension applied thereto. The freeend of'the arm 14 projects in the path of corn entering the bindingmechanism and engages with the corn prior to its engagement with thetrips 10 and 11, particularly when the corn is inclined at its upper endtoward the binder. This" arm serves to support a large portion of theweight and to thereby permit a full load to enter the binder mecha nism'before the trip is actuated. By adjustment of the spring, the propertension can be obtained to insure the proper load being received in thebinder at all times.

Since the construction hereinbefore set forth is capable of a certainrange of change and modification without materially departingfrom thespirit of the invention, I do not limit myself to such specificstructure except as hereinafter claimed.

I claim A supplemental trip attachment for a corn binder having a triphook mounted for swinging movement upon a vertical axis, comprising ahinge support adapted to be applied to the frame of the binder at apoint spaced from the axis of the trip hook, an arm pivoted at one endto the hinge member and arranged to swing in a plane transversely acrossthe axis of the trip hook, a spring connected at one end with the arm ata. point between the pivoted end thereof and the axis of the trip hook,and being connected at its other end with the frame of the binder at apoint in advance of the axis of the trip hook, said spring normallyholding the free end portion of the arm sub stantially in the verticalplane of the trip hook.

In testimony whereof I hereunto aflix my signature.

HOWARDF. LYMAN.
